reboot

reboot(8)						      System Manager's Manual							 reboot(8)

NAME

       reboot - Restarts the machine

SYNOPSIS

       /usr/sbin/reboot [-dlnq]

DESCRIPTION

       When  the  system  is running and multiple users are logged in, use the shutdown -r command to perform a reboot operation.  If no users are
       logged in, use the reboot command.

       The reboot command normally stops all running processes, syncs the disks, logs the reboot,  and	writes	a  shutdown  entry  in	the  login
       accounting file, /var/adm/wtmp.

       The  reboot command uses the sync call to synchronize the disks, and to perform other shutdown activities such as resynchronizing the hard-
       ware time-of-day clock.	After these activities, the system reboots.  By default, the system starts and the file systems are  automatically
       checked.  If the start-up activities are successful, the system comes up in the default run-level.

       You must have root privileges to use this command.  Using the -n flag can result in file system damage.

FLAGS

       Generates  a  crash  dump  of the system before halting it.  Can be used with any of the other flags.  Does not log the reboot using syslog
       Does not sync the disks or log the reboot using syslog Performs a quick reboot without first shutting down running processes; does not  log
       the reboot using syslog

EXAMPLES

       To  enable  the	default reboot action, enter: reboot This command causes the system to stop all running processes, sync the disks, log the
       shutdown, and perform other routine shutdown and reboot activities.  To shut down the system without logging the reboot, enter:	reboot	-l
       This  command  shuts  down  the	system and performs all shutdown and reboot activities, except logging the shutdown.  To reboot the system
       abruptly, enter: reboot -q This command reboots the system abruptly without shutting down running processes.

FILES

       Specifies the command path Specifies the login accounting file Specifies the path of the syslog daemon
